It’s been well over a year now that the IoT market has been battling against the ongoing industry-wide component shortages and this has no doubt caused huge financial losses for companies served by these chips. While this global crisis continues to linger on with no certainty as to...

ANT BBPS (breadboard power supply) is an open-source, compact power supply carefully designed to connect to the end of any M102 breadboard. It can be plugged directly into the power connection pins and does not interfere with anything else because of its unique shape. ANT BBPS offers an...

TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100mA - 1000mA) and an OLED display for monitoring. For battery charging the TP4056 is used. The TP4056 is a complete constant-current/constant-voltage linear charger for...

Not sure there is anyone on the internet who loves the Attiny series of microcontrollers as much as Stefan Wagner. We have explored a number of projects from him, from the USB power tester to the TinyRemote with ATtiny13, all based on a member of the Attiny series of microcontrollers....

USB power testers provide users with the opportunity of examining how much power a device plugged into a USB port is drawing from the port. While this is mostly used by designers who are building USB-powered devices and are trying to evaluate how much power it consumes, it is sometimes...

Measuring voltage and current is an important part of the development process for any hardware product. Especially when developing a low power device, the knowledge of how much power the device is drawing at each mode of its operation is critical to the correct estimation of its battery...

In this tutorial GreatScottLab will show us how to build a power meter and logger using Arduino and INA219 power monitor IC: In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power...

Juan Ignacio has designed a INA219 current sensor DIY Breakout board: Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface. For testing I used Rei VILO library with a MSP430G2553 and Energia, and I measured the...
